Kbuild doesn't seem to provide a way to override the Werror behvaiour from the top level. If a particular module uses -Werror, changing the top-level Makefile can't affect that. The only place I can see where -Werror gets overriden for an ARM kernel it in tools/perf. Is that where you were seeing the failure?
